Add vtkLinearCellExtrusionFilter
vtkLinearCellExtrusionFilter is a modeling filter.
It takes polygonal data as input and generates an unstructured grid data on output.
The input dataset is swept according to the input cell data array value along the cell normal and creates new 3D primitives.
Triangles will become Wedges, Quads will become Hexahedrons, and Polygons will become Polyhedrons.
